Check Digit Verification of cas no

The CAS Registry Mumber 191542-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,5,4 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 191542-63:
(8*1)+(7*9)+(6*1)+(5*5)+(4*4)+(3*2)+(2*6)+(1*3)=139
139 % 10 = 9
So 191542-63-9 is a valid CAS Registry Number.

π-Allylic sulfonylation in water with amphiphilic resin-supported palladium-phosphine complexes

Uozumi, Yasuhiro,Suzuka, Toshimasa

, p. 1960 - 1964 (2008)

π-Allylic substitution of allyl esters with sodium arylsul-finate was performed with an amphiphilic polystyrene-poly(ethylene glycol) (PS-PEG) resin-supported phosphine-palladium complex in water as a single reaction medium under heterogeneous conditions to give allyl sulfones in good to high yields. Catalytic asymmetric allylic substitution of cycloalkenyl esters also took place in water using a PS-PEG resin-supported chiral imidazo-indolephosphine- palladium complex to give cycloalkenyl sulfones with up to 81% ee.
